Uncensored fine-tune: trained to answer rather than refuse.

What it can do.

Reasoning

Thinks before it answers, and you can open the thinking to follow along.

Long-form writing

Stories, threads and scripts, up to ~1,200 words in one reply.

Instruction following

Steerable: the tone, character and rules you set are the ones it follows.

Coding and math

Trained on coding and math data, for working through problems and snippets.

How it's set up.
